Printing operation when printing one character
The printing operation for a 9 ✕ 9 dot matrix is explained in this section.
Characters are printed by energizing the respective print solenoids at the timing corresponding
to the head carriage movement position, using the carriage motor phase change signal as a
reference signal. The print head unit is moved approximately 0.339 mm by a one step rotation
(7.5°) of the carriage motor.
To print the number "2", printing solenoid numbers 2 and 9 are energized in sync with the
carriage motor phase change signal. Next, print solenoid number 8 is energized in sync with
TnH, delayed by a half dot time interval. The number "2" is printed by repeating this process.
